When recording infrasound waves or microwaves how do they vary from one another?
Ans) By microwaves, do you mean "radio signals", like in a microwave oven? These have nothing to do with sound. There is not a way to "record" microwaves really.
You can build a microwave transmitter with lots of power, sufficient to cook everyone in a building if you wanted to. The military has a microwave gun that heats up your skin painfully at a good distance
